Correct. In the case where you are given enough information to use the law of cosines you could in fact then use the law of sines afterwards to find your remaining angle. That being said beware of solutions that don't make a feasible triangle (if you were using the law of cosines you only have one angle, so that means whatever your second angle is that you found using the law of sines can't make your sum go over 180, because you still need some angle left for the last angle).
Answer:
2x + 6
Step-by-step explanation:
You multiply 2 by the numbers in parentheses. 2 times x is 2x, and 2 times 3 is 6.
Answer:
x = 6
y = 1
Step-by-step explanation:
to solve this system of equation we say let
2x + 3y = 15 .......................... equation 1
x - 3y = 3.................................. equation 2
from equation 2
x - 3y = 3.................................. equation 2
x = 3 + 3y.................................... equation3
substitute for x in equation 1
2x + 3y = 15 .......................... equation 1
2(3+3y) + 3y = 15
6 + 6y + 3y = 15
9y = 15 -6 ................................... combining the like terms
9y = 9
divide both sides by the coefficient of y
9y/9 = 9/9
y =1
put y = 1 in equation 3
x = 3 + 3y.................................... equation3
x = 3 + 3(1)
x = 3 +3
x = 6
therefore the value of x is 6 and y is 1 respectively
Divide 2.65 by 0.25
So 2.65/0.25= 10.6
So 10.6 ounces
Answer:
the answer would be f: y=-x^3 -4
Elaboration:
You don't show if there's a 4th answer so I'm just assuming you have one, but if there is no option, then I apologize.
Explanation:
y = -x^3 flips the equation, since you are putting the coefficient of x to a negative
y = -x^3 - 4 lowers the equation by 4 on the y axis, setting the equation shown in the graph.
